UNITED STATES PATENT OFFICE.

JOHANN FREDERICK MAX PATITZ,- 0F MILWAUKEE, WI SCONSIN, ASSIGNOR TO ALLIS- GHALMEFS COMPANY, OF MILWAUKEE, WISCONSIN, A CORPORATION OF NEW JERSEY.

To all whom it may concern:

Be it known that I, J OHANN FREDERICK MAX PATITZ, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a of which the following is a specification.

This invention relates to balancing Inachines or that class of devices by'which the light or heavy side of an object is deter mlned with respect to someaxis of the body, and specifically. it relates to means for preventing excessive tipping of a support upon which a body may be placed the balance of which is to be determined. v

Referring to the drawings which accompany this specification and form a part thereof and on which the same reference characters are used to. designatethe same elements in each of the several figures Figure 1 illustrates in elevation a balancing machine embodying this invention; Fig. 2 illustrates in elevation a modification; Fig. 3 illustrates an elevation of the apparatus shown in Fig. l, the view bein taken at rightangles to the view shown by Fi 1; and Fig. 4 illustrates a plan view 0 the apparatus.

Referring to the drawings, the numeral 1 designates a support or cross arm provided upon its lower side with, the hardened We 2 which are adapted to rest upon the hardened blocks 3 secured to beams 4, or supported in any other convenient and suitable way. Secured to the support 1 is the rod 5 which extends downwardly therefrom and which preferably also extends up through said support 1 so as to provide a stud upon which a turntable 6 is rotatably mounted, saidturntable being adapted to be retained in one of several'positions by means of any ordinary form of latching mechanism 7 secured to the support 1.

The term turntable as used herein refers to a table which is ready to serve as a weighingplatform in any position to which 'it may be turned and is contradistinguished from any such turning platform the object of whose turning is to space certain parts from knife edges with WhlCh they coact. Y

An electromagnet 8 is secured to the lower end of the rod 5, the wires leading thereto being carried up the shaft to a point near Specification of Letters Patent.

Application filed March 27,

the hardened Vs, as a convenient means for Patented June 13, 1911. 1907. Serial No. 364,858.

providing for movement of the shaft without interfering with said wires. Secured below said electromagnet 8 is an armature 9 which may be secured to the floor of a building or to any other suitable support.

The numeral 1O designates the switch of a controller or rheostat by which the flow of current through the wires 11 and the electromagnet may be controlled.

. The use and operation ofthe apparatus is 'as follows:' Abody, as, for example, a pulley, being placed upon the turntable 6 and properly centered with respect to the rod 5, will cause said turntable 6 to tip downwardly at that side of the pulley which is the heavier, the amount of tipping allowed being controlled through the switch 10 by the amount of current-supplied to the electromagnet 8. The turntable 6 being revoluble about the rod 5, enables the turntable with the object thereon to be turned so that with a given current the greatest tip is produced,

thereby indicating with precision the heavier side of the body. 7

. The details of the construction of the apparatus shown by Fig. 2, are in all essential particulars the same as those shown by Fig.

1, stops 12 being provided with either form of apparatus to prevent an excessive tipping of the turntable. The only difference -between the apparatus as shown by Fig. 2 from that as shown by Fig. 1 is in the fact that the electromagnet '80'is secured to the floor or other support while the armature 90 is secured to the rod 5, the wires leading to the electromagnet being changed to correspond with the change in its location.

What I claim is,

1. The combination with an oscillatable support, ofv a turntable carried thereby, a ro extended from said support, an electromagnet carried by said rod, and a stationary armature located adjacent said magnet 2. The combination with an 'oscillatable support, of a turntable'carried thereby, a

rod extended vertically from said support, an electromagnet carried hy'saidr'od, and a stationary armature located adjacent said.

said magnet, and means for energizing said other of said elements being stationary and magnet in varying degree as desired. located adjacent the other of said elements. 10

4. The combination with two elements one In testimony whereof, I aflix my signature an electromagnet and the other an armature in the presence of two witnesses.

for said magnet, an oseillatable support, a JOHANN FREDERICK mx PATITZ,

turntable carried by said support, and a rod Witnesses:
